I think its still going on, but the tram tour is going to be making detours, and I think that the tram will be going over near the animation buildings back behind there.
Backlot tour is still going. We were there on 7/3. I did notice that it has changed. One thing that I can remember that is different is that the Golden Girl's house is no longer.
Actually, the entire Residential Street is being demolished right now- including the Golden Girls facade- to make room for the stunt show. That's why there won't be any Osborne Lights this year.
The Backlot Tour doesn't include Residential Street but they did add some views of the animation studio as a compensation, which is more interesting than the Golden Girls & Ernest's house.
